Description

Technical Field

[0001] The utility model relates to the technical field of sound wave testers, in particular to a probe fixing device for a sound wave tester. Background Art

[0002] In ultrasonic tester detection technology, when dual probes are used to perform internal quality inspections on complex structures or specific materials, the testing method is to set one probe as the transmitting end, close to one side of the test piece, responsible for accurately emitting ultrasonic pulses into the interior. At the same time, the other probe is set as the receiving end, placed on the opposite side of the test piece, responsible for capturing and analyzing the information carried by these ultrasonic signals in the process of passing through the test piece. By analyzing the signal attenuation, time delay or waveform changes, technicians can accurately determine whether there are defects such as cracks and pores inside the test piece, locate their position and evaluate their properties.

[0003] In current ultrasonic testing practices, manual lifting is often used to place two probes on either side of the object being tested before testing. However, this method has been found to have the following drawbacks: the operator needs to keep their arms extended for a long time to stably place the two probes on either side of the object being tested. During this process, the constant tension in the arm muscles can easily cause soreness and fatigue. As the testing time increases, this physical discomfort not only affects the operator's concentration and work efficiency, but also directly leads to slight shifts in the probe position. Even small changes in probe position, which are imperceptible to the naked eye, can significantly affect the ultrasonic transmission and reception paths. This path inconsistency can interfere with the propagation characteristics of the ultrasonic signal, such as signal attenuation, propagation time, and waveform shape, resulting in the received signal not accurately reflecting the actual internal conditions of the object being tested. In addition, when the operator finds it difficult to maintain close contact between the probe and the object due to fatigue, the probe may unconsciously detach from the two sides of the object being tested, further exacerbating the errors in the test results. Utility Model Content

[0004] The utility model aims to solve the problems of operator fatigue, probe position deviation and separation from the tested object caused by manual lifting of the probe, thereby improving the accuracy and efficiency of detection, and proposes a probe fixing device for an acoustic wave tester.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Combine Figures 1-6 As shown, the present invention provides a probe fixing device for an acoustic wave tester, comprising a test piece 1 and two acoustic wave tester probes 2, wherein the two acoustic wave tester probes 2 are arranged on both sides of the test piece 1 and perform projection detection on the test piece 1, and further comprising:

[0037] A connecting fixture 3 is provided on the device under test 1;

[0038] Two crossbars 4 are provided on the connecting fixture 3 and are perpendicular to the device under test 1. The two crossbars 4 are connected to the left and right sides of the device under test 1 through the connecting fixture 3.

[0039] A locking member 5 is provided on the crossbar 4, wherein the locking member 5 is further provided with an L-shaped rod 6. The L-shaped rod 6 is arranged parallel to the object under test 1, and the number and distribution position of the L-shaped rod 6 are adapted to the locking member 5. The L-shaped rod 6 is connected to the left and right sides of the object under test 1 through the locking member 5;

[0040] The fixing mechanism 7 is arranged at the end of the L-shaped rod 6 and is interconnected with the ultrasonic tester probe 2, wherein the two ultrasonic tester probes 2 are tightly attached to the surface of the test piece 1 through the support of the cross bar 4 and the L-shaped rod 6 to fix the position of the ultrasonic tester probe 2.

[0041] First, the connecting fixture 3 is firmly set at the appropriate position of the test piece 1 as the basic support point of the entire fixing device. This step ensures that the subsequent components can be stably installed and fixed on the test piece 1. Then, two cross bars 4 are respectively installed on both sides of the connecting fixture 3. They are perpendicular to the test piece 1 and tightly connected to the left and right sides of the test piece 1 through the connecting fixture 3. The cross bars 4 serve as a horizontal support structure, providing a stable installation foundation for the subsequent L-shaped rods 6. Subsequently, locking members 5 are installed on the cross bars 4. These locking members 5 are not only used to fix the L-shaped rods 6, but also allow the position of the L-shaped rods 6 to be fine-tuned to ensure its parallel relationship with the test piece 1.

Then, the dynamic clamping piece 53 is also set on the base 51, and its clamping end is also in contact with the outer surface of the cross bar 4. At this time, the first hand-tightening screw 54 passes through the dynamic clamping piece 53 and is threadedly connected to the fixed clamping piece 52. By rotating the first hand-tightening screw 54, the distance between the fixed clamping piece 52 and the dynamic clamping piece 53 can be adjusted, thereby achieving stable fixation of the base 51 at different positions on the cross bar 4. This design allows the operator to flexibly adjust the position of the base 51 according to actual needs to adapt to different detection scenarios. Two elastic clamping plates 55 are fixedly installed on one side surface of the base 51. These two elastic clamping plates 55 have a certain elasticity and can clamp and fix the L-shaped rod 6. The L-shaped rod 6 is placed between the two elastic clamping plates 55, and is initially positioned by their clamping action. In order to further stabilize the position of the L-shaped rod 6 and allow fine-tuning thereof, a second hand-tightening screw 56 is designed.

By rotating the second hand-tightening screw 56, the distance between the two elastic clamping plates 55 can be adjusted, thereby achieving stable fixation of the L-shaped rod 6 at different positions. This design allows the operator to easily adjust the position of the L-shaped rod 6, and then adjust the position of the ultrasonic tester probe 2 on the test piece 1 to meet different detection needs.

A sliding groove is specially provided on the surface of the base 51. The shape, size and position of this sliding groove are carefully designed to ensure that it is adapted to the component to be installed. At the same time, a sliding block adapted to the sliding groove is fixedly installed on the dynamic clamping piece 53. This sliding block has a shape and size that matches the sliding groove to ensure that the two can fit closely and slide smoothly. During the assembly process, the dynamic clamping piece 53 The plate 53 is inserted into the sliding groove of the base 51 through the sliding block thereon. At this time, the dynamic clamping plate 53 can slide along the sliding groove on the surface of the base 51, thereby achieving clamping and fixation at different positions.

At the same time, this sliding connection method also facilitates subsequent maintenance and replacement work, and improves the practicality and durability of the entire locking member 5.

[0054] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 、 Figure 4As shown; a first threaded hole adapted to the first hand-tightening screw 54 is provided on the surface of the fixed clamping piece 52, a first through hole adapted to the first hand-tightening screw 54 is provided on the surface of the movable clamping piece 53, the first hand-tightening screw 54 passes through the first through hole and is threadedly connected to the first threaded hole, a second through hole adapted to the second hand-tightening screw 56 is provided on the surface of one elastic clamping piece 55, a second threaded hole adapted to the second hand-tightening screw 56 is provided on the surface of the other elastic clamping piece 55, the second hand-tightening screw 56 passes through the second through hole and is threadedly connected to the second The threaded holes are threadedly connected to each other. On the surface of the fixed clamping piece 52, a first threaded hole is specially opened to match the first hand-tightening screw 54. The inner side of this first threaded hole is provided with an internal thread that matches the external thread on the outer side of the first hand-tightening screw 54 to ensure that the two can be tightly and firmly threadedly connected.

As the second hand-tightening screw 56 rotates, it passes through the second through hole and gradually penetrates into the second threaded hole, thereby pushing the two elastic clamping pieces 55 closer to or away from each other, so as to achieve firm clamping of the L-shaped rod 6 at different positions.

[0055] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 、 Figure 6As shown; scale lines are set on the outside of the cross bar 4, and the fixing mechanism 7 is one of a clamp and a fixing sleeve.

By reading the scale lines, the operator can easily adjust the position of the probe to ensure that the distance and angle between the two probes are completely consistent, thereby improving the accuracy and reliability of the detection. At the same time, two optional fixing mechanisms 7 are provided to complete the connection and fixation between the probe and the L-shaped rod 6. The first is a clamp, which uses a clamping method to firmly fix the probe on the L-shaped rod 6. The clamp usually has an adjustable clamping force and angle to adapt to Probes of different shapes and sizes, and ensure that they can be firmly fixed in the predetermined position. The second type is a fixing sleeve, which is annular in shape as a whole, and the internal space matches the size of the probe. When fixing the probe, the operator only needs to insert the probe into the fixing sleeve to achieve a quick and stable connection. The design of the fixing sleeve is simple and effective, which not only simplifies the fixing process, but also improves the fixing efficiency. By combining the use of scale lines and fixing mechanism 7, the operator can adjust the position of the probe more accurately and flexibly, and ensure that they can be tested according to the predetermined requirements. This design not only improves the practicality and flexibility of the probe fixing device for the ultrasonic tester, but also enhances its adaptability and reliability, providing strong support for various detection tasks.

[0056] The specific working principle of the probe fixing device for an acoustic wave tester of the utility model is as follows:

[0057] First, firmly place the U-shaped seat 31 of the connecting fixture 3 on the outside of the DUT 1, ensuring that one inner surface of the U-shaped seat 31 is in close contact with one side surface of the DUT 1. Next, rotate the threaded rod 32 until it passes through the threaded hole of the U-shaped seat 31 and is threadedly connected to the U-shaped seat 31, while simultaneously driving the first clamping piece 33 toward the other side surface of the DUT 1 until the two are in close contact, thereby achieving preliminary fixation of the DUT 1.

[0058] Next, the two crossbars 4 are respectively installed in the two threaded seats 8 on the U-shaped seat 31. Since the outer side of the crossbar 4 near the U-shaped seat 31 is provided with an external thread that matches the internal thread of the threaded seat 8, the crossbar 4 can be detachably connected to the threaded seat 8 by rotating the crossbar 4. After installation, the two crossbars 4 are perpendicular to the test piece 1 and are tightly connected to the left and right sides of the test piece 1 through the connecting fixture 3, providing a stable horizontal support for the subsequent L-shaped rod 6.

[0059] Subsequently, a locking member 5 is installed under the crossbar 4. A fixed clamping piece 52 is fixed on the base 51 of the locking member 5, and its clamping end contacts the outer surface of the crossbar 4. A dynamic clamping piece 53 is also provided on the base 51, and its clamping end also contacts the crossbar 4. By rotating a first hand-tightening screw 54, the screw passes through the dynamic clamping piece 53 and is threadedly connected to the first threaded hole of the fixed clamping piece 52, so as to adjust the distance between the two and fix the base 51 on the appropriate position of the crossbar 4. The two elastic clamping pieces 55 on the base 51 are used to clamp the L-shaped rod 6. By rotating a second hand-tightening screw 56, the screw passes through one elastic clamping piece 55 and is threadedly connected to the second threaded hole of the other elastic clamping piece 55, so as to achieve a firm fixation of the L-shaped rod 6 on the base 51, and allows the position of the L-shaped rod 6 to be fine-tuned to ensure that it is parallel to the test piece 1;

[0060] Finally, a fixing mechanism 7 is set at the end of the L-shaped rod 6. The mechanism can be a clamp or a fixing sleeve. A suitable fixing mechanism 7 is selected according to actual needs, and it is connected to the ultrasonic tester probe 2. The probe is clamped with a clamp or the probe is inserted into the fixing sleeve to ensure that the two ultrasonic tester probes 2 are tightly attached to the surface of the test piece 1 through the support structure of the cross bar 4 and the L-shaped rod 6 respectively. At this time, the scale lines on the outside of the cross bar 4 and the L-shaped rod 6 can help the operator adjust the position of the probe to ensure that the probes on both sides are on the same horizontal plane, and the distance and angle are consistent. This close fixing method ensures close contact between the probe and the test piece, prevents the position of the probe from shifting or falling off during the detection process, and thus ensures the accurate transmission and reception of ultrasonic signals.
